The character of the A-100 is the same as that of the left A-10: Nubert advertises "honest" speakers. I can confirm that. They sound presence and crystal clear voices have body (which speaks for a strong mid range) and sound as close as if you had his ear directly behind the microphone. One must, it was said of "honesty" sake, get used to a little of the crystal-clear sound that can sometimes miss some heat because it just conceals or nothing "einsüßt". So really first trial hearing at least 14 days!
Poor or heavily compressed recordings sound now bad and spoil the joy. But good pictures are a big hit: the real fun and do not sound awkward, even at high volume levels - and the A-100 can Nupro loud!
A separate issue because of decisive importance for a good overall listening experience: the bass. The bass is astonishingly "right" exists, stronger than it suggests the size of the chassis - it is in the near field physically felt. Here the limits of physics seem moved. It is nice that in the electronic control options (the principle I will not explain here, s Nubert website.) The lower bass frequency is set: you can turn down the pits between 60 Hz and 160 Hz, which is fine if you - like me - can run with a small subwoofer: both can then be precisely adjusted to each other. (A small subwoofer for small money is to enjoy the music thoroughly recommended, eg Wavemaster Moody 2.1 - which makes power-but then the missing 35 Hz down deliberately). The A-100 bring fortunately with a separate subwoofer output.
I had, in addition to the old A-10 comparing with the Abacus C-Box (great PC speaker, significantly smaller package, a little less bass, no digital converter) and with the Audioengine A2 + (more than a quarter of the size of the A-100, beautiful warm sound, but not so clear-present, thinner bass, little adjustment, but digital converter USB). I opted for the A-100, it's the most fun.
Beautifully situated along the new A-100: There is now a magnetically adhering cover the speaker chassis, and each box brings a remote control, you have to change the settings only to a box, as the left speaker settings transmits digitally to the right - in the A-10 each box had its own analog controller.
One drawback: The volume control in the PC (via keyboard hot keys or mouse) does not work because when connected to the USB port, the A-100 bypasses all PC functions, because they prefer to do everything myself. So you have to press at each change in volume on the buttons on the left control box or the remote control to take (or rules in the media players, as long as their windows are active in the foreground). I help myself so: a remote control is mounted directly in front of me to reach the monitor base with Velcro dots, so that I may come up with a short handle. The other remote control can I use parallel and can be somewhere around - you get used to ...
What I miss, especially since my sound card is faulty in the PC: A small connector for a headphone jack on the front of the box would have been really nice ...
The speakers are quite excellent workmanship ("safe standard" housing, finely rounded edges), thoughtful and perfect the electronics. I have never seen active speaker, in which modern technology (fully digital signal processing, menu control, illuminated display can be switched off) and excellent sound quality have been combined in this way. True perfectionists respect to Nubert!
Yes, for the category "Computer Speakers" they cost you money, but what is offered, they are absolutely worth their price (had ordered B-goods with slight paint imperfections and small discount was ok). I would have preferred to take the A-200, but the place really is enough now not even the A-100 are not exactly small. Fact: Listening to music at work encounters with the A-100 in a new dimension in the direction of "real hi" and thus clearly at risk the working capacity of the owner - but it is now time for risks and side effects really good speakers ...
Will say: Full recommendation!
